Graph Methods |
The Graph type exposes the following members.
Methods| Name | Description | |
|---|---|---|
 | AddEdge |
Add an edge to the graph. The added edges requires a recommended identifier, a tail vertex, an head vertex, and a label.
Like adding a vertex, the provided object identifier may be ignored by the implementation.
|
| AddVertex |
Create a new vertex (of VertexType "default"), add it to the graph, and return the newly created vertex.
|
| AddVertex(Object) |
Create a new vertex (of VertexType "default"), add it to the graph, and return the newly created vertex.
|
| Clear |
Removes all edges and vertices from the graph.
|
 | CombineIntersection |
Combines to sets of edges by intersection
|
| ContainsVertex |
Returns a value indicating whether a Vertex exists for the specified vertex id.
|
| CountEdges |
Returns a count of all edges in this graph
|

If no edge is referenced by that identifier, then return null.

|
| GetEdges(String, Object) |
Return an iterable to all the edges in the graph that have a particular key/value property.
|
| GetEdgesT(String, T) |

|
| GetEdgeType | |
| GetValues |
Enumerates all the values for the given vertex/edge property
|
| GetVertex(Int32) |
Look up a Vertex |
| GetVertex(Object) |
Return the vertex referenced by the provided object identifier.
If no vertex is referenced by that identifier, then return null.
|
| GetVertexType | |
| GetVertices |
Return an iterable to all the vertices in the graph.
|
| GetVertices(String, Object) |
Return an iterable to all the vertices in the graph that have a particular key/value property.
|
| ImportGraphJson(String) |
Input the GraphJson JSON stream data into the graph.
In practice, usually the provided graph is empty.
|
| ImportGraphJson(Stream, Int32) |
Input the GrapJson JSON stream data into the graph.
In practice, usually the provided graph is empty.
|
| ImportGraphSon(String) |
Input the GraphSon JSON stream data into the graph.
In practice, usually the provided graph is empty.
|
| ImportGraphSon(Stream, Int32) |
Input the GraphSon JSON stream data into the graph.
In practice, usually the provided graph is empty.
|
| NewEdge(EdgeType, Vertex, Vertex) |
Creates a new edge instance.
|
| NewEdge(EdgeType, PropertyType, Object, PropertyType, Object) |
Creates a new edge instance.
The tail of the edge will be any node having the given tailV Value for the given tailAttr Property identifier,
and the head of the edge will be any node having the given headV Value for the given headAttr Property identifier.
|
| NewEdgeProperty |
Creates a new Property.
|
| NewEdgeType(String, Boolean, EdgeType) |
Creates a new edge type.
|
| NewEdgeType(String, Boolean, VertexType, VertexType, EdgeType) |
Creates a new edge type.
|
| NewVertex |
Creates a new node instance.
|
| NewVertexProperty |
Creates a new Property.
|
| NewVertexType |
Creates a new node type.
|
| Open |
Opens a graph
|
| Persist |
Persists this object. Override in your subclasses when you want fields of your class to be persisted in some special way.
(Overrides OptimizedPersistablePersist(Placement, SessionBase, Boolean, Boolean, QueueIOptimizedPersistable).) |
| Query |
Generate a query object that can be used to fine tune which edges/vertices are retrieved from the graph.
|
| RemoveEdge |
Remove the provided edge from the graph.
|
| RemovePropertyType |
Removes a property type except if any vertex or edge is using it
|
| RemoveVertex |
Remove the provided vertex from the graph.
Upon removing the vertex, all the edges by which the vertex is connected must be removed as well.
|
| RemoveVertexType |
Removes a VertexType from this graph. An exception is thrown if the VertexType is in use.
|
| Select(PropertyType, FuncIComparable, IComparable, Boolean, IComparable) |
Enumerates all elements satisfying the given condition for the given property and value
|
| Select(PropertyType, FuncIComparable, IComparable, IComparable, Boolean, IComparable, IComparable) |
numerates all elements satisfying the given condition for the given property and value range
|
| Shutdown |
A shutdown function is required to properly close the graph.
This is important for implementations that utilize disk-based serializations.
|
| ToString |
Displays class name plus object id
(Overrides OptimizedPersistableToString.) |
| Traverse |
Selects all neighbor Vertices from or to each of the node OID in the given collection and for the given edge type.
|
| Unpersist |
Removes an object from the persistent store and makes the object a transient object. It does not automatically make referenced objects unpersisted. Best way to do so is to override this virtual function in your own classes.
(Overrides OptimizedPersistableUnpersist(SessionBase).) |
Extension Methods| Name | Description | |
|---|---|---|
 | AddEdge |
Add an edge to the graph with specified id and provided properties.
(Defined by GraphHelpers.) |
| AddVertex |
Add a vertex to the graph with specified id and provided properties.
(Defined by GraphHelpers.) |
| CopyGraph |
Copy the vertex/edges of one graph over to another graph.
The id of the elements in the from graph are attempted to be used in the to graph.
This method only works for graphs where the user can control the element ids.

| GraphString | (Defined by StringFactory.) |
| LoadGml | (Defined by GraphHelpers.) |
| LoadGraphml | (Defined by GraphHelpers.) |
| LoadGraphson | (Defined by GraphHelpers.) |
| ReIndexElementsT |
For those graphs that do no support automatic reindexing of elements when a key is provided for indexing, this method can be used to simulate that behavior.
The elements in the graph are iterated and their properties (for the provided keys) are removed and then added.
Be sure that the key indices have been created prior to calling this method so that they can pick up the property mutations calls.
Finally, if the graph is a TransactionalGraph, then a 1000 mutation buffer is used for each commit.
